Pretty close. The problem is generally that gettydefs and/or stty is clearing
the CLOCAL bit on a serial line without the modem control signals wired up.
The software approach is to change gettydefs to keep CLOCAL on, while the
hardware approach is to wire the cable to either pass DCD through or to
force it high.  Also, using an absolutely-no-modem-control device should
do the trick as well.
